audit: cycle 0037 — drift-clean (bound params in the graph model + viewer)
Close-audit for cycle 0037 (commit range d069484..47e0e60). Architect drift review
against the design ledger + CLAUDE.md domain invariants: no contract drift, no debt.
No regression scripts are configured (the architect is the gate); build + test +
clippy verified green independently by the orchestrator.
cycle 0037 (clean):
- C23 preserved: bind still resolves the slot name to a fixed position and re-splices
the value in the build closure; BoundParam/"bound" is recorded purely beside that
capture, a render/debug symbol dropped at lowering — bootstrap and the run loop
never read bound_params() (only the model serializer does). The compilat stays
index-wired. A genuine twin of the cycle-0035 instance-name thread.
- C14 preserved: the inline no-bind model_golden (sample_root) is byte-unchanged;
the "bound" field is conditional (mirrors "name"), so unbound nodes are
byte-identical, and only the sample fixture's blend node gained the field.
scalar_str is total over all four Scalar variants and deterministic (f64 via {:?}
keeps a decimal point so a bound f64 never reads as an i64).
- C12/C19 preserved: the tunable surface is untouched — bind still removes the slot
from schema.params; the eight-param sweep pins stay byte-identical with weights[2]
absent. The render annotation reads from a separate bound vec, not param_space().
Test coverage: the original-position unit test (trailing + reverse-chained), the
prim_record conditional-field unit test (i64 + f64), and a headless render guard
pinning slot-order faithfulness for both a trailing and a middle bind (the middle
case catches an append-only regression).
Resolution: carry-on. Next iteration: pick the next backlog item.
